Marburg virus (MARV) and Ravn virus (RAVV) of the species Orthomarburgvirus marburgense are the causative agents of Marburg virus disease (MVD). The disease has a case fatality ratio of up to 88%, but it can be much lower with good and early patient care. Both viruses are part of the Filoviridae family (filovirus).
Marburg virus disease (MVD), formerly known as Marburg haemorrhagic fever, is a severe, often fatal illness in humans. The average MVD case fatality rate is around 50%. Case fatality rates have varied from 24% to 88% in past outbreaks.
🦇 Rousettus aegyptiacus, a fruit bat of the Pteropodidae family, is considered the natural host of Marburg virus. The virus is transmitted to people from fruit bats and spreads among humans through human-to-human transmission.
